Of course when I need it I can not find it.
There is another techdoc for "Basic troubleshooting steps for library and tape drives in AIX".

Since the os see the library and the drives, but the library is unknown within the TSM Server.

1. Power down the tape library, halt the TSM Server application.
If the TSM Server is hosted on a Windows system, once the TSM Server is halted, power down the system.
2. Power up the library.
3. Once the library complete its power, then restart the TSM Server.
If the TSM Server is hosted on Windows, power up the system and restart the TSM Server.
